:PIPE CLEANER.

Application led December l, 1926, Serial No. 152,031, and in CanadaNovember 11, 1926.

This invention relates to new and useful improvements in cleaningdevices for tobacco pipes, and the like, and the object of the inventionis to provide a cleaning attachment which will allow the pipe to beeasily connected to a source of compressed iluid supply, whereby anyobstruction in the pipe may be cleaned out by the passage of thelluid'therethrough.

Another object is to provide a cleaning device for smoking devices,which will be constructed to suit various sizes of pipe bowls, andcigarette or cigar holders, without the necessity of adjusting same.

A further object is to provide a cleaning device which will be simple inconstruction and comparatively inexpensive to manufacture, and whichwill be easily and conveniently carried in the pocket of the user.

In my invention I provide a cleaning device, the main body of which ismade of resilient material so shaped that it will fit into various sizesof pipe bowls, cigarette holders and cigar holders, and seal same, sothat a blast of air may be passed through said attachment into the pipeor like smoking device, to clear the passage of same of any obstruction.

In the drawings which illustrate various forms of my invention Figure 1is a sectional side elevation of a tobacco smoking pipe with my cleaningattachment fitted thereto.

Figure 2 is a sectional elevation of one modification of the deviceshown in Figure 1.

Figure 3 is a plan view of the attachment shown in Figure 2.

Figure 4 is a side elevation of my device used to clear obstructionsfrom a cigarette holder.

Referring more particularly to the drawings, A designates a pipe bowlhaving they usual shank B, which is recessed to receive vthe mouthpieceC. The shank and mouthpiece are bored to provide a smoke passageway D.My cleaning device is used for cleaning said passageway of anyobstruction which may tend to blocksame.

In Figure 1 which shows one form of my invention, 11 designates thevalve at the discharge end of a hose connected to a source of compressedair supply, such as is used for supplying air to automobile tires at aservice station, or to an Ordinar hand pump. My cleaning device ts intot e bowl of the pipe and is provided with a portion which lits into thevalve so that the air supplied from a pump or hose line may be used forcleaning the pipe. The device comprises a threaded stem 12, the lowerend 13 of which may be flanged, as shown. Thestem is bored to allow airto pass therethrough. Moulded around the. shank is the truncatedconeshaped plug 14, which is made of resilient material. The plug isprovided'with an enlarged llange 15, the edge 16 of which may beserrated or knurled. A pressure plate 17 may be fitted 'over the stemand held in place by the threaded nut 18. The lower end of the plug hasprojectingl downwardly therefrom a smaller truncated cone-shaped portion19, adapted to fit into the ends of the pipe stems or cigarette holders,as shownA in Figure 4. The plug has aY centrally disposed aperture whichregisters with the 'aperture in the stem. In the Ymodified type shown inFigure 2, the stem extends through the plug, designated 20', and may betapered towards said end in a somewhat similar manner as the projectingportion 19 of the device shown in Figure 1. When the devicel is used onthe larger types of pipe bowls, a rubber sleeve 21 is used, the lowerend of which is made thicker than the remaining portion, so that it willfit tightly around the outer wallof the pipe bowl when in use. The upperend 22 of said sleeve engages with the knurled edge of the flangedportion of the plug, as shown inxFigure 2.

The sleeve when not in 'use maybe rolled up clear of the bowl, as shownin dotted lines in Figure 2. ,Modifications may be made in the generalconstruction of the ldevice Without departing from the spirit oftheinvention.

In operation the plug is pressed' into the bowl of a pipe or into theend of a cigar or cigarette holder. The plug being of a resilient naturelits closely against the walls and forms a sealing means to prevent airfrom passing between the plug and the surfaces of the smoking device itcomes in contact with. The end of the plug is connected to the end ofthe hose to raise the valve 11 therein and allow air under pressure topass into the pipe to clear out any matter which tends to clog up thepassageways in the pipe. When the device is used for pipes having alarger bore than the plug, thefsleeve forms the sealing medium. It willbe readily seen that e. device constructed in the manner hereindetailed,

rovides-asimple pipe attachment which can Re used una' vamety of pipesof dierent bores or 0n pipe Shanks, cigarette holders,

cigar holders, and the like, without making any adjustments to the plug.It is very simple and comparatively inexpensive to manu facture andprovides an eiicient device for use in cleaning out the smokepassageways of tobacco smoking devices. It is of a compact nature andmay be conveniently carried by the user of same. f

Having thus described my invention, what I claim is l. In a pipecleaning attachment, a threaded stem, a frusto-conically shaped bodyportion of resilient material secured to part of the stem, a resilientflange on said body portion adapted to contact with the upper edge ofthe bowl of a pipe, a pressure plate secured to the stem and contactingwith the upper surface of the flange, a smaller rustoconically shapedextension formed integral and projecting downwardly from the bottom ofthe body portion, yand means formed in the stem, the body portion, andits extension, to allow for the passage of air therethrough.

2. A cleaning device for tobacco pipes and the like comprising a body ofresilient material formed with. a central air passage and presentingfrusto-conical portions of different mean diameters with a shoulderbetween said portions, the portion of larger mean diameter being adaptedto plug the mouth of a pipe bowl and the portion of smaller meandiameter being adapted to plug cigarette and cigar holders.

In witness whereof I have hereunto set my hand. v
